Be assigned to the quantity of the piece of passage 0: i
Be assigned to the quantity of the piece of passage 1: j
Be assigned to the quantity of the piece of passage 2: k
Be assigned to the quantity of the piece of passage 3: m
The delivery time of each piece: x (m second)
Each piece is to the time of writing of optical record medium: y (m second)
n＝i+j+k+m
From passage 0 beginning sequential write, and data block is arrived passage 1, passage 2 and passage 3 by order assignment.
In this case, after the beginning, beginning that passage 1 is write is x * i (m second) in passage 0.Therefore, in passage 0, write end position, the quantity of data block reduces x * i/y.This is by following formulate.
J=i-x * i/y=(1-x/y) * i ... formula 1
In a similar fashion, obtain following formula.

M=(1-x/y) * k ... formula 3
According to these formula, j, k and m count i by the piece of distributing to passage 0 respectively and represent.
J=(1-x/y) * i ... formula 4
K=(1-x/y)
2* i ... formula 5
M=(1-x/y)
3* i ... formula 6
By delivery time x, write time y and the quantity allotted of passage 0 represented the quantity allotted to all passages.
In optical recording apparatus 1, write under the situation that time y is a constant in supposition,, then can confirm quantity allotted each passage if obtained delivery time x.
That is, the quantity n of all data blocks of record is represented as n=i+j+k+m.The formula below if formula 4, formula 5 and the formula 6 of representing above-mentioned j, k and m by i respectively by substitution n=i+j+k+m, then obtain.
n＝i+(1-x/y)×i+(1-x/y)
2×i+(1-x/y)
3×i
Therefore, count n, delivery time x and write time y according to the piece that has obtained, the piece that can obtain to distribute to passage 0 is counted i.
Then, obtained i after, with i substitution formula 4, formula 5 and formula 6, thereby calculate j, k and m.
At this, because the delivery time is shorter about writing the time, so the piece that can distribute and more equate.If the delivery time is 0, then all allotments equate.In fact, the delivery time is limited, makes allotment different mutually.
Through measuring delivery time and the distribution of control, can make the end time point of the time of writing of all passages identical each other to each passage.
